The LT5578 mixer is a high performance upconverting mixer optimized for frequencies in the 0.4GHz to 2.7GHz range. The single-ended LO input and RF output ports simplify board layout and reduce system cost. The mixer needs only 1dBm of LO power and the balanced design results in low LO signal leakage to the RF output. At 1.95GHz operation, the LT5578 provides conversion gain of 0.7dB, high OIP3 of 24.3dBm and a low noise floor of 158dBm/Hz at a 5dBm RF output signal level.
